The present disclosure is to be considered as an exemplification of the various inventions, and is not intended to limit the disclosure to the specific embodiments illustrated by the figures or description below.

Referring now to FIGS. 1A-1D, a simplified version of the leg actuator mechanism is provided in accordance with an example embodiment of the present disclosure. As shown, various embodiments of the leg actuator mechanism include an upper leg mechanism 1, a lower leg mechanism 5, a mounting 2, an upper follower connector 3, and a lower follower connector 4.

In various embodiments, the mounting 2 defines a follower pathway configured to receive a follower joint C1. As shown, the upper follower connector 3 and the lower follower connector 4 are operably coupled at the follower joint C1. For example, the first upper follower end of the upper follower connector 3 may be operably coupled to the first lower follower end of the lower follower connector 4 at the follower joint C1. In various embodiments, the upper follower connector 3 may be affixed to the upper leg mechanism 1 at the second upper follower end (e.g., the end at joint B1) between the hip end (e.g., the end at hip joint A) of the upper leg mechanism 1 and the knee end (e.g., the end at lower knee joint B2) of the upper leg mechanism 1. In various embodiments, the lower follower connector 4 may be affixed to the lower leg mechanism 5 between the first end (e.g., lower knee joint B2) and the second end (e.g., heel joint D) of the lower leg mechanism 5 at the second lower follower end (e.g., the end at joint C2). In some embodiments, the upper leg mechanism 1 and the lower leg mechanism 5 may be operably coupled at the lower knee joint B2.

In various embodiments, as the follower joint C1 travels around the follower pathway 2, the upper follower connector 3 and the lower follower connector 4 move and in accordance with these movements, the upper leg mechanism 1 and the lower leg mechanism 5 also move between varying degrees of bent and straightened positions about the lower knee joint B2.

Referring now to FIG. 1A, the leg actuator mechanism is in a first position, such that the follower joint C1 is positioned at the bottom of the follower pathway 2. In such an embodiment, in an instance the follower joint C1 is positioned at the bottom of the follower pathway, the angle defined between the upper leg mechanism and the lower leg mechanism may be greater than 90 degrees. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism may be greater than 120. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism may be greater than 150. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism may be slightly less than 180 degrees (e.g., between 150 degrees and 180 degrees).

In some embodiments, the angle defined between the angel defined between the upper leg mechanism 1 and the lower mechanism 5 may be approximately the same as the angle defined between the upper leg mechanism 1 and the upper follower connector 3 (e.g., the angle defined between Joint A, Joint B1, and Joint C1). Additionally, in some embodiments, the angle defined between the upper leg mechanism 1 and the upper follower connector 3 (e.g., the angle defined between Joint A, Joint B1, and Joint C1) may be approximately the same as the angle defined between the lower follower connector 4 and the lower leg mechanism (e.g., the angle defined between Joint C1, Joint C2, and Joint D).

Referring now to FIG. 1B, the leg actuator mechanism moves into a second position as the follower joint C1 travels clockwise along the follower pathway 2. As the leg actuator mechanism moves from the first position to the second position, the angle defined between the upper leg mechanism and the lower leg mechanism may reduce only slightly (e.g., less than 30 degrees). In some embodiments, the combination of the upper leg mechanism 1 and the lower leg mechanism 5 may be rotated about hip joint A (e.g., hip joint A may be stationary).

Referring now to FIG. 1C, the leg actuator mechanism moves into a third position as the follower joint C1 continues to move along the follower pathway 2 (e.g., in the third position, the follower joint C1 may be positioned directly above the follower joint position when in the first position, shown in FIG. 1A). As the follower joint C1 moves from the second position (FIG. 1B) to the third position (FIG. 1C), the lower follower connector 4 moves the lower leg mechanism 5 such that the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be reduced from the angle defined in the first position and/or the second position. For example, the angle defined between the upper leg mechanism and the lower leg mechanism may less than 120 degrees. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism may be less than 90 degrees. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism may be less than 60 degrees.

Referring now to FIG. 1D, the leg actuator mechanism moves into a fourth position as the follower joint C1 continues to move along the follower pathway 2. In various embodiments, as the follower joint C1 travels along the follower pathway 2, the angle defined between the upper leg mechanism and the lower leg mechanism may increase from the third position. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism at the fourth position and the second position may be the same (e.g., with the heel joint D rotating around hip joint A). In various embodiments, as the follower joint C1 is driven around the follower pathway 2 (e.g., such as discussed below), the leg actuator mechanism may rotate through each position shown in FIGS. 1A-1D (see also FIGS. 1E-1H as a further example).

In various embodiments, the follower pathway may define an elliptical pathway. In some embodiments, the placement of the heel joint D may be based on the position of the follower joint C1 along a first direction (e.g., along a horizontal direction along the x-axis shown in FIG. 1A) in the follower pathway 2. In various embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be based on the position of the follower joint C1 along a second direction (e.g., along a vertical direction along the y-axis shown in FIG. 1A) within the follower pathway 2. In various embodiments, the first direction and the second direction may be approximately 90 degrees apart from another (e.g., the first direction and the second direction may form approximately a right angle). While the first direction and second direction discussed in reference to FIG. 1A are approximately horizontal and vertical respectively, the axes may be rotated, such that the first direction is not along the horizontal axis and/or the second direction is not along the vertical axis. In various embodiments, the first direction and the second direction may be defined based on the position of A relative to the follower pathway. For example, Joint A may be in the first direction relative to the follower pathway (e.g., Joint A may be a fixed pivot point for the leg actuator mechanism).

In further exemplary embodiments, the follower pathway may be defined by a rotating mounting. Referring now to FIGS. 1E to 1H, a simplified version of the leg actuator mechanism with a rotating mounting is provided in accordance with an example embodiment of the present disclosure. As shown, in FIGS. 1E-1H, various embodiments of the illustrated example leg actuator mechanism include an upper leg mechanism 1, a lower leg mechanism 5, an upper follower connector 3, a lower follower connector 4, a follower joint C1, a follower joint connector Z3, and a rotating mounting 12.

In various embodiments, the rotating mounting 12 defines a rotating follower pathway configured to drive the follower joint C1 to travel in accordance with the follower pathway defined by the rotating mounting 12 (e.g., along the follower pathway). In various embodiments, the pathway is defined along the circumference of the rotating mounting 12. For example, the rotating mounting 12 may comprise a disc, where the pathway is defined along the circumference of the disc. As shown, a first end of the follower joint connector Z3 may be operably coupled to the both the upper follower connector 3 and the lower follower connector 4 at the follower joint C1. In various embodiments, the follower joint C1 may comprise an attachment member (e.g., a pin, and/or the like) configured for coupling the follower joint connector Z3 and the upper follower connector Z3 at the follower joint C1.

A projecting member Z4 (e.g., pin, rod, and/or the like) coupled to the rotating mounting 12 may extend through at least a portion of an opening defined by the follower joint connector Z3 and may be configured to drive the follower joint connector Z3 in an oscillatory manner as the mounting 12 rotates. For example, the opening defined by the follower joint connector Z3 may allow the rotational motion of the mounting 12 to oscillate the bottom end of the follower joint connector Z3. The rotating mounting 12 may be configured to rotate about the axis of a rotating mounting member Z2. The rotating mounting member Z2 may comprise an axle, a shaft, or the like. In various embodiments, the follower joint connector Z3 may comprise and/or otherwise describe a horizontal swing clockwise and/or counter-clockwise actuator.

As further shown, a second end of the follower joint connector Z3 may be operably coupled to a vertical-moving member Z1. The follower joint connector Z3 may be operably coupled to a mounting disc assembly 6 configured as a part of the leg actuator mechanism. The vertical member Z3 may be operably coupled to the mounting disc assembly 6 via an attachment mechanism Z5 (e.g., pin, and/or the like) The vertical-moving member Z1 may comprise or otherwise describe a vertical up and down actuator. In various embodiments, the vertical-moving member Z1 may be configured to move upwardly and downwardly as the mounting 12 rotates. As shown, in some embodiments, the vertical moving member Z1 may have a defined range of motion (e.g., Z1 min to Z1 max). The position of the vertical moving member Z1 within the defined range of motion may depend on the position of the rotating mounting 12. As described above, the upper follower connector 3 may be coupled to the follower joint connector Z3 at the follower joint C1, and follower joint Z3 may be coupled to the vertical-moving member Z1. In various embodiments, as the mounting 12 rotates, causing the follower joint connector Z3 and the vertical-moving member Z1 to travel in accordance with their respective motion, the follower joint connector Z3 and the vertical-moving member Z1, in turn, drive or otherwise cause the follower joint C1 (thus, the upper follower connector 3) to travel in accordance with the follower pathway defined by the rotating mounting 12.

As noted above, the rotating mounting 12 may be configured to drive the follower joint C1 to travel in accordance with the follower pathway defined by the mounting 12. For example, the follower joint C1 may remain tangent to the follower pathway defined by the rotating mounting 12 as the mounting 12 rotates. As described above, the upper follower connector 3 and the lower follower connector 4 may be operably coupled at the follower joint C1. For example, the first upper follower end of the upper follower connector 3 may be operably coupled to the first lower follower end of the lower follower connector 4 at the follower joint C1. In various embodiments, the upper follower connector 3 may be affixed to the upper leg mechanism 1 at the second upper follower end (e.g., the end at joint B1) between the hip end (e.g., the end at hip joint A) of the upper leg mechanism 1 and the knee end (e.g., the end at lower knee joint B2) of the upper leg mechanism 1. In various embodiments, the lower follower connector 4 may be affixed to the lower leg mechanism 5 between the first end (e.g., lower knee joint B2) and the second end (e.g., heel joint D) of the lower leg mechanism 5 at the second lower follower end (e.g., the end at joint C2). In some embodiments, the upper leg mechanism 1 and the lower leg mechanism 5 may be operably coupled at the lower knee joint B2.

In various embodiments, as the follow joint C1 travels in accordance with the follower pathway defined by the rotating mounting 12, the upper leg mechanism 1 and the lower leg mechanism 5 also move between varying degrees of bent and straightened positions about the lower knee joint B2.

Referring now to FIG. 1E, the leg actuator mechanism is in a first position, such that the follower joint C1 is positioned at the bottom of the follower pathway defined by the rotating mounting 12. In such an embodiment, in an instance the follower joint C1 is positioned below the follower pathway defined by the rotating mounting 12, the angle defined between the upper leg mechanism and the lower leg mechanism may be greater than 90 degrees. In some embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be greater than 120 degrees. In some embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be greater than 150 degrees. In some embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be slightly less than 180 degrees (e.g., between 150 degrees and 180 degrees).

In some embodiments, the angle defined between the upper leg mechanism 1 and the lower mechanism 5 may be approximately the same as the angle defined between the upper leg mechanism 1 and the upper follower connector 3 (e.g., the angle defined between Joint A, Joint B1, and Joint C1). Additionally, in some embodiments, the angle defined between the upper leg mechanism 1 and the upper follower connector 3 (e.g., the angle defined between Joint A, Joint B1, and Joint C1) may be approximately the same as the angle defined between the lower follower connector 4 and the lower leg mechanism (e.g., the angle defined between Joint C1, Joint C2, and Joint D).

Referring now to FIG. 1F, the leg actuator mechanism moves into a second position as the mounting 12 rotates clockwise causing the follower joint C1 to travel clockwise in accordance with the follower pathway defined by the mounting 12. As the leg actuator mechanism moves from the first position to the second position, the angle defined between the upper leg mechanism and the lower leg mechanism may reduce only slightly (e.g., less than 30 degrees). In some embodiments, the combination of the upper leg mechanism 1 and the lower leg mechanism 5 may be rotated about hip joint A (e.g., hip joint A may be stationary).

Referring now to FIG. 1G, the leg actuator mechanism moves into a third position as the mounting 12 continues to rotate causing the follower joint C1 to continue to travel in accordance with the follower pathway defined by the mounting 12. (e.g., in the third position, the follower joint C1 may be positioned directly above the follower joint position when in the first position, shown in FIG. 1E). As the follower joint C1 moves from the second position (FIG. 1F) to the third position (FIG. 1G), the lower follower connector 4 moves the lower leg mechanism 5 such that the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be reduced from the angle defined in the first position and/or the second position. For example, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be less than 120 degrees. In some embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be less than 90 degrees. In some embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be less than 60 degrees.

Referring now to FIG. 1H, the leg actuator mechanism moves into a fourth position as the mounting 12 continues to rotate causing the follower joint C1 to continue to travel in accordance with the follower pathway defined by the mounting 12. In various embodiments, as the follower joint travels in accordance with the follower pathway defined by the mounting 12, the angle defined between the upper leg mechanism and the lower leg mechanism may increase from the third position. In some embodiments, the angle defined between the upper leg mechanism and the lower leg mechanism at the fourth position and the second position may be the same (e.g., with the heel joint D rotating around hip joint A). In various embodiments, as the follower joint is driven to travel in accordance with follower pathway defined by the mounting 12 (e.g., such as discussed below), the leg actuator mechanism may rotate through each position shown in FIGS. 1E-1H.

In various embodiments, the follower pathway may define an elliptical pathway. In various embodiments, the follower pathway may define a non-elliptical pathway. In some embodiments, the placement of the heel joint D may be based on the position of the follower joint C1 along a first direction (e.g., along a horizontal direction along the x-axis shown in FIG. 1E) in the follower pathway 2. In various embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be based on the position of the follower joint C1 along a second direction (e.g., along a vertical direction along the y-axis shown in FIG. 1E) within the follower pathway 2. In various embodiments, the first direction and the second direction may be approximately 90 degrees apart from another (e.g., the first direction and the second direction may form approximately a right angle). While the first direction and second direction discussed in reference to FIG. 1E are approximately horizontal and vertical respectively, the axes may be rotated, such that the first direction is not along the horizontal axis and/or the second direction is not along the vertical axis. In various embodiments, the first direction and the second direction may be defined based on the position of A relative to the follower pathway. For example, Joint A may be in the first direction relative to the follower pathway (e.g., Joint A may be a fixed pivot point for the leg actuator mechanism).

Referring now to FIG. 2A-2B, the components shown in the leg actuator mechanism are approximated to the human body in accordance with an example embodiment of the present disclosure. As shown, the hip joint A corresponds to the pelvis and/or hip region of a human body. In various embodiments, the hip joint A may be fixed during movement. In some embodiments, the upper leg mechanism 1 may approximate the femur bone of a leg. Additionally, the lower knee joint B2 may approximate the knee of a leg. In some embodiments, the lower leg mechanism 5 may be approximated as a shin bone and the heel or ankle of a human may approximated as the heel joint D. In various embodiments, the angle defined between the upper leg mechanism 1 and the lower leg mechanism 5 may be the same as the angle defined between the femur and the shin.

Referring now to FIGS. 3A-3B, a portion of a leg actuator mechanism is provided in accordance with an example embodiment of the present disclosure. In some embodiments, a leg actuator mechanism may include a mounting disc assembly 6 configured as a part of the leg actuator mechanism. In various embodiments, the femur mounting connector 6 connects the femur 7 a (shown in FIGS. 4A-8 ) to the mounting disk 6 b. In some embodiments, the mounting disc 6 b may define the follower pathway 2 configured to receive the follower joint C1 (as shown in FIG. 3B, the bolt 6 e). In various embodiments, the angle defined between the femur 7 a and the shin 7 c (shown in FIGS. 4A-8 ) may be based on the position of the follower joint C1 along the second direction within the follower pathway and the position of the foot of the leg actuator mechanism may be based on the position of the follower joint C1 along the first direction within the follower pathway. In some embodiments, the upper follower connector 3 shown in FIGS. 1A-1D may correspond to link 6 d. In various embodiments, the driving disc 6 c may be configured to drive the follower joint C1 (as shown in FIG. 3B, the bolt 6 e) about the follower pathway. In various embodiments, the driving disc 6 c may be activated by a driving mechanism (e.g., as discussed below in reference to FIGS. 9-10 ).

Referring now to FIGS. 4A-4D, four different leg positions are shown in accordance with an example embodiment of the present disclosure. In various embodiments, the four positions of the leg actuator mechanism shown in FIGS. 4A-4D correspond to the four positions discussed in reference to FIGS. 1A-1D and FIGS. 1E-1H. As shown in FIGS. 4A-4D, the positions of the leg actuator mechanism simulate the movement of a leg during movement (e.g., walking or running).

As shown, the movement between the first position through the fourth position simulates the movement of a leg. Referring now to FIG. 5 , a cut-away view of the leg actuator mechanism is shown in accordance with the first position shown in FIG. 4A. In various embodiments, the femur 7 a may correspond to the upper leg mechanism 1 shown in FIGS. 1A-1D and FIGS. 1E-1H. In some embodiments, the internal femur link 7 b may correspond to the lower follower connector 4 shown in FIGS. 1A-1D and FIGS. 1E-1H. In some embodiments, the shin 7 c may correspond to the lower leg mechanism 5 shown in FIGS. 1A-1D and FIGS. 1E-1H. In various embodiments, the angle defined between the femur 7 a and the shin 7 c may be slightly less than 180 degrees.

Referring now to FIG. 6 , a cut-away view of the leg actuator mechanism is shown in accordance with the second position shown in FIG. 4B. As discussed in reference to FIG. 1B above, as the follower joint C1 travels along the follower pathway, the upper leg mechanism (e.g., the femur 7 a) and the lower leg mechanism (e.g., the shin 7 c) rotate about the hip joint A (shown in FIG. 3 ). Similarly, as discussed in reference to FIG. 1F above, as the follower joint C1 travels in accordance with the defined follow pathway, the upper leg mechanism (e.g., the femur 7 a) and the lower leg mechanism (e.g., the shin 7 c) rotate about the hip joint A (shown in FIG. 3 ). Additionally, as the leg moves from the first position to the second position, the angle defined between the femur 7 a and the shin 7 c may begin to decrease. In various embodiments, the angle between the femur 7 a and the shin 7 c may have a predetermined range of motion. For example, in some embodiments, the range of motion may be from approximately 45 degrees to 180 degrees. In various embodiments, the range of motion may be based on the use case (e.g., the range of motion of the angle defined between the femur 7 a and the shin 7 c may be similar to the range of motion of a human femur and shin). In some embodiments, the angle between the femur 7 a and the shin 7 c may exceed 180 degrees (e.g., to simulate a wider range of motion). In such an embodiment, the Joint A may remain stationary, while other components may operate in a mirrored position.

Referring now to FIG. 7 , a cut-away view of the leg actuator mechanism is shown in accordance with the third position shown in FIG. 4C. As discussed in reference to FIG. 1C above, as the follower joint C1 travels along the follower pathway from the second position to the third position, the angle defined between the upper leg mechanism (e.g., femur 7 a) and the lower leg mechanism (e.g., shin 7 c) may continue to decrease. Similarly, as discussed in reference to FIG. 1G above, as the follower joint C1 travels in accordance with the defined follower pathway from the second position to the third position, the angle defined between the upper leg mechanism (e.g., femur 7 a) and the lower leg mechanism (e.g., shin 7 c) may continue to decrease. Additionally, the shin 7 c (and subsequently the foot of the leg) may begin to move forward based on the movement along the follower joint C1.

Referring now to FIG. 8 , a cut-away view of the leg actuator mechanism is shown in accordance with the fourth position shown in FIG. 4D. As discussed in reference to FIG. 1D above, as the follower joint C1 continues to travel along the follower pathway from the third position to the fourth, the angle defined between the upper leg mechanism (e.g., femur 7 a) and the lower leg mechanism (e.g., shin 7 c) begins to increase. Similarly, as discussed in reference to FIG. 1H above, as the follower joint C1 continues to travel in accordance with the defined follower pathway from the third position to the fourth, the angle defined between the upper leg mechanism (e.g., femur 7 a) and the lower leg mechanism (e.g., shin 7 c) begins to increase. In various embodiments, the angle defined between the upper leg mechanism (e.g., femur 7 a) and the lower leg mechanism (e.g., shin 7 c) may be the same as the angle in the second position. In various embodiments, in an instance the follower joint C1 continues to travel along the follower pathway in the clock-wise direction, the leg actuator mechanism would move from the fourth position back to the first position. In an instance the follower joint C1 moves clock-wise around the follower pathway, then the leg actuator may simulate forward motion (e.g., forward walking or running). In an instance the follower joint C1 moves counter-clockwise around the follower pathway, then the leg actuator may simulate backward motion (e.g., backward walking or running).

Referring now to FIGS. 9A-10B, a doll is provided in accordance with an example embodiment of the present embodiment. As shown, the doll includes a driving mechanism 12 configured to activate the movement of the driving disc 6 c shown in FIG. 3B. In various embodiments, the driving mechanism 12 may be partially or completely internal and/or external.

In an example embodiment, shown in FIG. 9B, the driving mechanism 12 may have a mounting bracket 12 a. In some embodiments, the mounting bracket 12 a may be part of the internal and/or external structure of a doll. In some embodiments, the driving mechanism 12 may have one or more driving inserts (e.g., internal driving insert 12 a and/or external driving insert 12 d) configured to receive a driver insert (discussed in reference to FIG. 11 below). In various embodiments, as shown in FIG. 9B, the driving inserts may be configured to rotate such that the rotational motion from the driver insert may be transferred to the driving mechanism 12 and subsequently to the driving disc 6 c. In various embodiments, the driving mechanism 12 may include one or more links configured to translate the rotational motion between different items (e.g., 12 j).

By way of example, a driver insert (not shown) may be attached to the driving insert 12 d and transfer rotational motion into the driving mechanism 12. In such an example, the rotational motion may be translated between the driving insert 12 d and the disc 12 c (e.g., via operably coupling). The disc 12 c may then be coupled to the arm mechanism 12 b (e.g., to move the arms during motion). Additionally, the rotational motion of the driving insert 12 d may be transferred to disc 12 f. In such a case, the disc 12 f may be coupled to the link 12 h such that the rotational motion is translated to the disc 12 i, which is operably coupled with the driving disc 6 c (shown in FIG. 3 ). Various embodiments would be evident to one of ordinary skill in the art based on the disclosure provided herein. FIGS. 10A and 10B also show additional angles of the driving mechanism 12 interaction with the mounting assembly 6 discussed herein.

In various embodiments, as shown in FIGS. 9A-10B, the doll 8 may be configured with a plurality of leg actuator mechanisms (e.g., one for each leg). In some embodiments, the driving mechanism 12 may be configured to activate a plurality of leg actuator mechanisms simultaneously (e.g., two legs may be offset to allow for accurate running simulation for two legs). Additionally, the driving mechanism 12 may be used to rotate one or more arm mechanisms as discussed herein. In some embodiments, the rotational movement of a driving insert (e.g., 12 e and/or 12 d may result in a plurality of leg actuator mechanisms and arm mechanisms to be moved. For example, the one driving insert may provide rotational movement for two legs and two arms (e.g. for a humanoid doll). Various other animals (e.g., legged animals) may also be simulated using various embodiments discussed herein. In some embodiments, different character (e.g., humanoid doll or animal) may have a follower pathway defined specifically based on that character. For example, the length of the follower pathway may be longer to simulate a larger leg motion. In some embodiments, multiple follower pathways and/or follower mechanisms may be used to simulate more complex motions (e.g., to simulate animals with multi jointed legs).

Referring now to FIGS. 11A-11B, multiple views of a carrier mechanism 10 are provided in accordance with an example embodiment of the present disclosure. In various embodiments, the carrier mechanism 10 may include a driving control means (e.g., a steering wheel and/or handle bars 10 a). In some embodiments, the carrier mechanism 10 may optionally have an impact barrier 10 b to protect the doll during operation. In some embodiments, the existence of the impact barrier 10 b may be based on the material of the doll (e.g., a doll made out of a cushioning material, such as polyurethane foam, may not need to be as protected). In various embodiments, the carrier mechanism 10 may include a doll latch 10 c configured to removably attach the doll to the carrier mechanism. Additionally, as discussed in reference to FIGS. 12-13 , the carrier mechanism may include a vehicle latch 10 d configured to removably attach the doll to the carrier mechanism 10. In some embodiments, the carrier mechanism may be unitary with the vehicle. Various carrier mechanisms 10 may be used in order to transfer rotational motion to the driving mechanism 12 discussed above and FIGS. 11A-13 are merely illustrative of an example embodiment.

As show in FIG. 11C, the driver insert 10 e may be configured to mate with a driving insert (e.g., driving insert 12 e) such that the rotation of the driver insert 10 e may be transferred to the driving mechanism 12. In various embodiments, the driver insert 10 e may be in communication with one or more wheels of the carrier mechanism 10 (e.g., the rotational movement of the wheels may be transferred to the driver insert 10 e via a pulley or link).

Referring now to FIGS. 12 and 13 , a movement doll system is provided in accordance with an example embodiment. Referring now to FIG. 12 , the doll 8, the carrier mechanism 10, and the vehicle 11 are provided detached from one another. Referring now to FIG. 13 , the doll 8 may be attached to the carrier mechanism 10 as discussed above (e.g., operably coupling of the driving insert and the driver insert). Additionally, the vehicle 11 may be attached to carrier mechanism 10 via the vehicle latch 10 d discussed above. In some embodiments, the vehicle 11 and the carrier mechanism 10 may be unitary (e.g., a specially designed vehicle with the carrier mechanism included). In various embodiments, other types of vehicles 11 may be used. For example, the vehicle may be a recreational vehicle, such as a bicycles, scooters, miniature cars, radio-controlled cars, and skateboards, or the like. In various embodiments, the vehicle may be specially designed for a given doll (e.g., to be used as a set). Additionally or alternatively, the carrier mechanism 10 may be an attachment to an existing vehicle (e.g., a carrier mechanism may be attached to a bicycle).

Various embodiments discussed herein allow for dolls to simulate motion (e.g., running and/or walking) in a more realistic fashion that allows for a more immersive user experience. For example, embodiments discussed herein allow for a doll to “run” along with a child when riding a vehicle, such as a bicycle or scooter or the like.

FIGS. 300D-30F illustrate front views of a handlebar assembly 302, wheel and fork assembly 304, pulley assembly 308, and gear and shaft assembly 310, according to some embodiments. FIGS. 30G shows angled views and a side view of the handlebar assembly 302, the wheel and works assembly 304, the pulley assembly 308, the gear and shaft assembly 310, and the central rotating axis 312, according to some embodiments.

Operation of the aforementioned mechanism 300 and its various assemblies and components will now be described, according to some embodiments and with respect to various figures previously described.

In some embodiments, as shown in at least FIG. 21 , the wheel WF2 of the wheel and fork assembly 304 may rotate about the axel WF3 of the wheel and fork assembly 304. In other embodiments, the lower pulley P1 of the pulley assembly 308 may be latched to the wheel WF2 and thereby also rotate about the axel WF3 as the wheel WF2 rotates. In further embodiments, the lower pulley P1 may transfer rotational motion to the belt P2. In some embodiments, the belt P2 may transfer rotational motion to the upper pulley P3. In other embodiments, the upper pulley P3 may then transfer rotational motion to the miter gear P4 of the pulley assembly.

Referring now to at least FIG. 23 , in further embodiments, the miter gear P4 may then transfer rotational motion to the second central miter gear CM5 of the central mount assembly 306, which, in some embodiments, may then transfer rotational motion to the free spin shaft CM2, also of the central mount assembly 306. In some embodiments, the free spin shaft CM2 may be mechanically latched to the ball bearing CM3, and item CM3 may, in some embodiments, cause the free spin shaft CM2 to freely rotate. It will be understood that, according to some embodiments, CM2 may rotate freely independent of the direction of the wheel WF2.

Referring now to at least FIG. 24 , the direction of the wheel WF2 may be controlled by the handlebar assembly 302, which may be mechanically latched to the fork and free spin shaft bracket CM1 of the central mount assembly 306 (further detail shown in at least FIG. 18 ).

Referring now to at least FIG. 26 , understanding that, in some embodiments, the free spin shaft CM2 may rotate freely and/or independently of the direction of the wheel WF2, the free spin shaft CM2 may transfer rotational motion to the miter gear CM4, which may, in some embodiments, transfer rotational motion to the first miter gear of the second set B1 of the gear and shaft assembly 310. In at least this way, the central mount assembly 306 may transfer energy to the gear and shaft assembly 310. At least for the reason that the first miter gear of the second set B1 may be mechanically latched to the free spin shaft bracket CM1, the direction of the first miter gear of the second set B1 may be controlled by the handlebar assembly 302. In other embodiments, the first miter gear of the second set B1 may transfer rotational motion along the various elements of the second set (B2-8) such that the first miter gear of the second set B1 transfers rotational motion to the fifth miter gear of the second set B8, which, in some embodiments, may transfer rotational motion to the mechanical leg actuation mechanism. Further, in some embodiments, the miter gear CM4 may transfer rotational motion to the first miter gear of the first set A1, which may similarly transfer motion along the various elements of the first set (A2-8) such that the first miter gear of the first set A1 transfers rotational motion to the fifth miter gear A8. It will be understood that the first miter gear of the first set A1 is not mechanically latched to the forks and free spin shaft bracket CM1—therefore, the direction of A1 is not controlled by the handlebar assembly 302. However, the first miter gear of the first set A1 is mechanically latched to the bicycle 301 by the gear mounting bracket F7. In some embodiments, the fifth miter gear A8 may transfer rotational motion to the mechanical leg actuation mechanism by means of the shaft A9 and miter gear A10, as illustrated in at least FIG. 25 .

By at least the operation described previously in this disclosure, and as shown in FIGS. 14-30I, the front-back steering alignment mechanism 300 may allow a user of the bicycle 301 (or any example vehicle) to control a doll (e.g., the horse doll 400) such that, if a user turns the handlebar assembly 302 in one direction, the front of the doll 402 remains aligned with the rear of the doll 404. For example, if a user tilts the handlebar assembly 302 toward the right, the front of the doll 402 will tilt toward the right, while the rear of the doll 404 will tilt to the left, remaining aligned. Similarly, if a user tilts the handlebar assembly 302 toward the left, the front of the doll 402 will tilt left, while the rear of the doll 404 tilts to the right, remaining aligned.
